The larvae feed on dead wood.

Taxonomy

E. sulphurella was first described scientifically by J.C. Fabricius in 1775. Subsequently, the same scientific name was used for several other moths, creating a number of junior homonyms that are all invalid. These include:

History

According to some theories, the foundation of the town would be linked to the destruction of the Roman colony of Interamna Lirenas, although the first historically documented human presence date to the foundation of several monasteries, with the annexed boroughs, by the Abbey of Montecassino (10th century).

The name "Esperia" was chosen in 1867 when the current frazioni of Roccaguglielma and San Pietro merged into a single municipality, with the former as the municipal seat.

The type species of Esperia (originally described as Tinea orbonella, now E. sulphurella) has some differences versus the type species of Dasycera (originally described as T. aemulella, now E. oliviella), but these are slight and at present it is not determined whether they justify the maintenance of two small genera versus a more comprehensive genus containing two subgenera.
